Description

SMART POWER SUPPLY FOR ELECTRIC VEHICLE CHARGERS

FIELD

[0001] The improvements generally relate to the field of energy storage systems, and, in particular, the improvements generally relate to the field of battery-based energy storage systems for charging electric vehicles.

INTRODUCTION

[0002] Energy storage systems are useful for charging electric vehicles (EVs). Charging systems for electric vehicles can be referred to as EV charging systems, or EV chargers. The prevalence of and society’s dependence on EVs is growing which in turn creates an increasing need for EV chargers.

[0003] Energy storage systems have energy storage elements such as batteries or battery packs. Each battery or battery pack may have one or more battery modules, and each battery module may have one or more battery cell. Battery charging may be optimized at the battery pack level, the battery module level, or the battery cell level, depending on the connection access available at each of these levels. There exists a need for energy storage systems with flexibility for charging and discharging batteries.

[0004] Energy storage systems can be stationary or mobile. There exists a need for mobile or portable energy storage systems. Mobile or portable charging systems with batteries may provide advantages such as increased charging rate, less cost, more efficiency and so on.

[0005] There also exists a need for stationary energy storage systems that may provide advantages such as increased charging rates, less cost, and more efficiency.

[0006] Stationary EV charging systems designed for residential housing generally connect to 120 volt electrical connections (Level 1 charging) or 208 volt to 240 volt electrical connections (Level 2 charging) already available at the property. Level 1 chargers generally take 8 to 36 hours to fully charge (from empty to full) a single EV depending on the size of the EV battery pack. Level 2 chargers generally take 4 to 21 hours to fully charge a single EV depending on the size of the EV battery pack and the current rating of the electrical connection to the property from the electrical grid. Both Level 1 and Level 2 chargers take a long time to fully charge an EV. When compared to vehicles with internal combustion engines which can be fully filled at a refuelling facility in a few minutes, Level 1 and Level 2 chargers may not be feasible for fast charging at commercial charging facilities.

[0007] If fast charging is desired either at commercial or residential facilities, a fast DC charging system (Level 3) is required. Level 3 chargers can fully charge a single EV in 10 minutes to 1 hour. These charging times may decrease further as DC fast charging technologies improve. However, installing level 3 charging systems requires 3-phase power connections at the charging location. Installing 3-phase power connections is very costly and not practical or even feasible in some cases. As such, there exists a need for EV charging stations with integrated battery packs or other energy storage devices which may be fully charged over a long period of time (such as overnight) and then able to fast charge EVs quickly from the stored energy.

[0008] Stationary charging systems with batteries may provide advantages such as increased charging rate, less cost, less installation cost, more efficiency and so on.

[0009] For EV charging systems, there exists a need for power supply systems to provide electrical power to the EV charging system. Further, for mobile and stationary EV charger systems, there exists a need for mobile and stationary power supply systems. In addition, there is a need for multiple input (charging) mechanisms, and multiple output (discharging from battery and charging to EV) mechanisms to provide flexibility and adaptability for different EV charging systems and battery technologies.

[0010] Further, EV charger technology and protocol changes, and also the battery technology changes. For example, EV charger technology changes to meet different EV drivers’ requirements, such as different types of EV charging ports (including but not limited to CCS Types I and 2, CHAdeMo, Tesla, J1772, GB/T, and IEC 62196 Type 2), and different types of mobile EV Charger battery charging methods (including but not limited to AC 110V, AC 208V to 240V, and DC 400V to 900V). These changes create challenges for systems with EV charger technology and battery technology.

[0011] Accordingly, there is a need for power supply systems for EV charger systems with multiple input (charging) mechanisms, and multiple output (discharging from battery and charging to EV) mechanisms to provide flexibility and adaptability for different EV charging and battery technologies. [0012] As the demand for EV chargers increases, so does the demand on the electrical power grid. The electrical power grid cannot support fast charging of hundreds of thousands of electric vehicles simultaneously, especially during peak electricity demand hours. Also, it is desirable to have an intelligent charging solution that monitors the power load at the charging location and adjusts the EV charging rate and power to minimize the impact on the power load at the location. As such, there exists a need for fast charging capability without significantly impacting the electrical power grid or the power load at the charging location.

[0013] In some cases, there is a need for backup power at an EV charging location when there is an electrical power outage. There is also a need for power at remote sites where there is no connection to the electrical grid. In such cases, the standard solution is the use of an electrical generator powered by a combustion engine (usually gasoline or diesel). As the world focuses on green energy and reducing carbon footprints, there is a need for cost-effective, environmentally friendly backup power or remote power supply solutions.

[0014] EV batteries store a considerable amount of energy, in some cases over 100 kWh. The energy storage capacity of batteries in EVs is expected to exceed the storage capacity of all other stationary green energy storage system in the near future. The ability to use the energy stored in EV batteries as backup power during power outages or remote power at sites with no electrical power connection is beneficial and desirable. Thus, there exists a need for bidirectional EV charging solutions where in addition to providing electrical power for systems charging an EV, the energy stored in system batteries can be used to provide backup power and remote power by reversing the direction of electrical charge flow.

[0067] The smart power supply system with energy storage 100 has a main battery control board 501 that has a plurality of battery pack connectors 505, 506, 507, 508, 509 connected to battery packs 551 , 552 and other additional battery packs 553, 554. The battery packs have one or more battery modules 611 , 612, 613, 614 and may have a battery management system board 601. Each battery module has one or more battery cells. If battery management system board 601 is present, the charging and discharging of the battery packs are controlled by a battery management system board 601 that communicates with the main battery control board 501 to monitor each battery pack and battery module status, and control the charging and discharging of the individual battery modules inside the battery pack. In some embodiments, each battery module may also have a battery management system board 601 to control the charging and discharging of each battery cell. In such cases, these battery management system boards 601 also communicate with the main battery control board 501 to monitor each battery module and battery cell status. The main battery control board 501 may send charging instructions to battery management system boards 601 to alter the charging and discharging techniques and/or parameters if the battery management system boards 601 have this capability. The main goal of controlling the charging and discharging at the battery module and battery cell level is to compensate for inferior modules and cells and improve the overall life of the battery pack by preventing individual battery module and battery cell failures. The main battery control board 501 has a plurality of input charging connectors. For example, the input ports may include a DC input charging port 302, an AC input charging port 316, AC grid power charging port 321. The main battery control board 501 has a battery control chip 520 that monitors battery pack status, battery module status (if information is available from battery pack), battery cell status (if information is available from battery pack), and controls and monitors charging and discharging of the battery packs, of the battery modules (if battery pack has this feature) and the battery cells (if battery pack has this feature). The main battery control board 501 and battery control chip 520 may control charging parameters including but not limited to voltage level, current level, voltage waveform, current waveform, and pulsed or continuous charging, depending on the condition of the battery, load requirements, environmental conditions, and other external factors.

[0068] The main battery control board 501 is connected to the main control system board 110 through a connector 530 on the main battery control board 501 and a connector 130 on the main control system board 110. The main control system board 110 is a central control system that monitors and controls the main battery control board 501 , wireless communication board 801, and LCD control board 201. The main control system board 110 controls a plurality of output power connections 141, 142, 143, 144, 145. For example, the DC output discharging connection 401 may be connected to the output power connection 142 while the AC output charging port 402 may be connected to the output power connection 141. The smart power supply with energy storage 100 may have multiple types of output power connections if required. For example, the output power connection may include extra AC output charging ports 143, 144, 145. The main control system board 110 programs how to allocate the charging and discharging of the battery packs through the connection to the main battery control board 501. For example, if two or more EVs 901, as shown in Fig. 8B, are connected through two or more EV chargers (1200), they may simultaneously be provided power or only one of the EV chargers (1200) may be provided power. The main control system board 110 decides which battery packs will be used for providing power to EV chargers 1200 for charging the EVs 901 and how much power is drawn from each pack. The main control system board 110 decides which battery packs are charging and which battery packs are discharging at a given time. The main control system board 110 has a main control chip 120 that controls the main control system board 110. The main control system board 110 may have inputs from external sensors 710, the information from which may aid in optimizing charging and discharging settings based on environmental and other external parameters. These external sensors may include but are not limited to ambient air sensors 711, humidity sensors 712, solar light sensors 713, and power load sensors 714. Accordingly, the main battery control board 501 has a battery control chip 520, and the main control system board 110 has a main control chip 120. For instance, the power load sensor 714 may be used to sense the electrical load at the charging location and if the load is extremely high, to limit the AC power input to the smart power supply with energy storage 100 so as not to put additional strain on the electrical system at the charging location.

[0069] The main control system board 110 is configured to control a plurality of output power connections 141, 142, 143, 144, 145. These output power connections 141 , 142, 143, 144, 145 can be a plurality of different types of connections for different EV charging systems. In some embodiments, the output power connections 141, 142, 143, 144, 145 are not EV charging ports that couple directly to EVs, but instead the output power connections 141 , 142, 143, 144, 145 can connect to EV chargers with EV charging ports that in turn connect to the EVs. For example, the output power connections 141, 142, 143, 144, 145be power cables or connections for DC EV chargers, AC EV chargers, AC grid sockets and so on. The smart power supply system with energy storage 100 can have different configurations for the main control system board 110 for different types of connectors that depend on the desired type of connected devices. For example, if it is desired for the smart power supply system with energy storage 100 to connect to a DC EV Charger, then, in an example embodiment, the smart power supply system with energy storage 100 can have DC Connector 142. If it is desired for the smart power supply system with energy storage 100 to connect to an AC EV Charger, then, in an example embodiment, the smart power supply system with energy storage 100 can have AC connector 141. If it is desired for the smart power supply system with energy storage 100 to connect to one or more home appliances, then the smart power supply system with energy storage 100 can have connections 143, 144.

[0070] Figure 2B illustrates an example of the main control system board 110 and connections to external sensors 710 and the other control boards 201, 501, 801 of a smart power supply with energy storage 100.

[0071] Fig. 3A illustrates an example connection between the main battery control board 501 and battery pack 551 of a smart power supply with energy storage 100 for an EV charging system. In this example, the main battery control board 501 connects to one battery pack 551. In other examples, the main battery control board 501 connects to multiple battery packs. See for example, Fig. 5 which shows the main battery control board 501 connecting to multiple battery packs 552, 553.

[0072] Fig. 3B illustrates an example connection between the main control system board 110 and other display and communications boards of an example smart power supply with energy storage 100, or smart power supply with energy storage for an EV charging system.

[0073] The main control system board 110 is a management system that monitors input electric power from the input ports to battery packs, output electric power from the output power connections to the one or more loads, and battery status for the battery packs (and battery modules and battery cells if the information is available). The main control system board 110 and the main battery control board 501, which together may also be referred to as a main battery management controller, controls a switching matrix 720. The switching matrix 720 consists of five switch banks. An example of a switching matrix with two input ports, two output power connections, and four battery packs is shown in Fig. 12. The input switch bank 725 switches control which input sources are used to charge the battery packs. The output switch bank 726 switches control which output loads the battery packs discharge into. The charging switch bank 722 controls which battery packs are charged from the input ports, while the discharging switch banks 723 control which battery packs discharge to the output power connections. The inter-battery switch bank 721 enables battery packs to be connected in series to increase the charge voltage. The inter-battery switch bank 721 also enables any of the battery packs to charge any of the other battery packs which is useful to maintain all batteries at a minimum charge capacity to increase battery life and improve battery efficiency. All switch banks are controlled by the main control system board 110 and the main battery control board 501. The charging and discharging rates of the battery packs may be controlled by pulsing the switch banks on and off at a specific duty cycle or by adding current limit 730 circuitry in each series with the battery pack connections. The switching matrix is part of the main control system board 110 and main battery control board 501.

[0074] The main control system board 110 provides a management system that separately controls charging of the battery packs from input power and discharging of the battery packs to the EV chargers (or other type of loads). The main control system board 110 limits discharging rate of the battery packs to connected loads based on remaining charge percentage and status of the battery packs, and the power requirements of the connected load, such as an EV charger, if known. For instance, if the EV is 80% charged already and the driver of the EV has two hours to spare and this information is provided to the smart power supply with energy storage by the EV charger, the charging rate may be set to a low level to improve battery pack life. The main control system board 110 has a security system that controls the authentication of users.

[0075] The switching matrix 720 connects the plurality of battery packs and the plurality of inputs, and the plurality of battery packs and the plurality of outputs. The switching matrix 720 selectively connects each battery pack to any number of the plurality of input ports or any number of the plurality of output power connections, each input port to any number of battery packs, and each output power connection to any number of battery packs. The switching matrix 720 is part of the main control system board 110 and main battery control board 501.

[0076] The main battery control board 501 is operably coupled to the switching matrix 720 for controlling connections between each battery pack and any number of the input ports or any number of the plurality of output power connections.

[0077] Fig. 3A illustrates an example connection between the main battery control board 501 and battery pack 551 of an example smart power supply with energy storage 100, or smart power supply with energy storage for an EV charging system. The main battery control board 501 controls output power delivery parameters, such as voltage, and communicates with the main control system board 110 to obtain the desired rate at which to provide output power based on sensor inputs, the requirements of the load, such as EV charger 1200, and other parameters. The main control system board 110 may have pre-set programs so that the main battery control system 501 may combine the voltage from battery packs 551 with other available battery packs, such as battery pack 552, and provide a higher voltage to the main control system board 110. The main control system board 110 may then provide a higher voltage for EV charging to DC output discharging connection 401 and AC output discharging connection 402.

[0078] Fig. 3B illustrates an example connection between the main control system board 110 and some other boards in the system such as the LCD control board 201 , main battery control board 501, and wireless communication board 801, of smart power supply with energy storage 100, or a smart power supply with energy storage for an EV charging system. The main control system board 110 may send data via connectors 151 and 250 to the LCD control board 201. [0079] Fig. 4A shows an example battery pack 551 containing battery modules 611, 612, 613, 614. The battery pack 551 has a plurality of battery modules 611 , 612, 613, 614. The battery pack 551 connects to battery management system board 601 generally located inside the battery pack. The battery modules 611, 612, 613, 614 provide energy storage capacity for the battery pack 551.

[0080] Fig. 4B shows example connections for the battery modules 611 , 612, 613, 614 of the battery pack 551 and the battery management system board 601.

[0081] Fig. 5 illustrates an example connection of multiple battery packs 551 , 552 to increase performance by enabling additional charge capacity, increased changing voltage, and increased charging rate. The main battery control board 501 may connect to multiple battery packs 551 , 552 to increase the charging voltage if desired. For example, if battery pack 551 and battery pack 552 each have 400 volt capability and they are both connected in series via the interbattery switch bank 721 , this increases the overall voltage that can be provided by the smart power supply with energy storage 100. By using this technique, the main control system board 110 may have one output power connection (401) and a connected EV charger 1200 that is able to handle high voltage. As shown in Fig. 8B, the main battery control board 501 could provide 800 volts from the two battery packs connected in series to the main control system board 110. The main control system board 110 may control the output voltage to provide the EV charger 1200. If more than two battery packs are connected to the system, different charging voltages may be provided to different output power connections. For example, DC output connection (401) may be set to 800 volts DC by combining battery packs 551 and 552, while output connection (402) may be set to 400 volts AC from the third battery pack 553.

[0082] The smart power supply with energy storage 100 may have connectors 505, 506 to connect the battery packs 551 , 552 to the main battery control board 501. The smart power supply system with energy storage 100 may have additional battery pack upgrade connectors 507, 508, 509 to connect to additional battery packs. The main battery control system 501 may have a battery control chip 520 and a connector 530 to the main control system board 110.

[0083] Fig. 6A illustrates an example connection of an external battery pack to the smart power supply with energy storage 100. The connectors 511 , 512 on the rear panel may be allocated to battery packs 551 , 552 which connect to main battery control board 501 through connectors 505, 506 of the main battery control board 501. The connectors 507, 508, 509 (or battery pack upgrade connectors) of the main battery control board 501 may be allocated to connect to additional (e.g. external) battery packs 553, 554 through the unused connector sockets 513, 514 on the rear panel of EV charger 100.

[0084] Fig. 6B shows the connections to the main control system board 110 from the external switches and sensors 710. The smart power supply system with energy storage 100 has a start button 701 and an emergency stop button 702 that provide input to the main control system board 110 when activated by an operator of the smart power supply with energy storage 100. The functionality of the start button 701 and an emergency stop button 702 may be complemented by remote control internal switches controlled via an external wireless remote control, an app on a personal handled device (PDA) connected wirelessly, or a network connection (wired or wireless) from an external computer or similar network device. The smart power supply with energy storage 100 may have selectable switches, such as input charging port switch 703, that establish the connection between components for charging and discharging and manually control the switching matrix 720, and/or may have remote control internal switches controlled via an external wireless remote control, an app on a personal handled device (PDA) connected wirelessly, or a network connection (wired or wireless) from an external computer or similar network device. The main control system board 110 may have inputs from external sensors 710, the information from which may aid in optimizing charging and discharging settings based on environmental and other external parameters. These external sensors may include but are not limited to ambient air sensors 711 , humidity sensors 712, solar light sensors 713, and power load sensors 714.

[0085] Fig. 7A shows an example of power distribution control from the main battery control board 501 to the multiple discharging output power connections with output connectors 141, 142, 143, 144, 145. Power is distributed from the main battery control board 501 to the main control system board 110 and output power connectors 141 , 142, 143, 144, 145. The battery control chip 520 can be programmed with configurations for battery pack charging and discharging for a plurality of battery packs 551, 552, 553, 554. Charging and discharging are distributed through a current path from the main battery control board 501 to the main control system board 110 and output power connectors 141, 142, 143, 144, 145. The main control system board 110 has a connector 151 to the LCD control board 201 to provide data and parameter settings relating to power distribution and the discharging ports. Fig. 7A shows an example main control chip 120 of the main control system board 110. The main control chip 120 may be programmed with all configurations for output power connections 141 , 142, 143, 144, 145. Output power connection 141 may be a normal AC output connection supporting Level II charging. Output power connection 142 may be a fast charging high voltage DC output connection supporting Level III charging. Output power connection 143 may be a fast charging high voltage 3 phase AC output connection supporting Level III charging. Output power connection 144 and 145 may be normal AC output connections supporting Level II charging. The main control chip 120 may command and control the main battery control board 501 and communicate with a main computing server 1005, as shown in Fig. 10, through the wireless communication board 801. The main control system board 110 automatically detects connections to the discharging ports. The main control system board 110 automatically implements power distribution across the discharging output power connections.

[0086] Fig. 7B illustrates an example of the main control board system 110 and the main battery control board 501 controlling the discharge characteristics of the battery packs along with the output power requirements of the loads. In this example, the system draws more load charge current from battery pack 551 since it has a high percentage of charge remaining and draws less current from battery pack 552 since it has a low percentage of charge remaining. The main control board system 110 is the overall control mechanism of the smart power supply with energy storage 100, and all components of the smart power supply with energy storage 100 may be automatically controlled by programming the main control chip 120.

[0087] Fig. 8A illustrates an example smart power supply system with energy storage 100 using the main control system board 110 to simultaneously provide power to multiple EV chargers 1200 to charge multiple EVs 901. The main control system board 110 may have multiple discharging power connections or output power connectors 141, 142, 143, 144, 145 to connect to different EV chargers 1200. In turn, the EV chargers 1200 connect to EVs 901. The main control system board 110 individually controls the discharging to EV chargers 1200 to control how much power or voltage is delivered to each EV charger 1200. The main control system board 110 can deliver different levels of power or voltage to different EV chargers 1200. Each EV charger 1200 may receive different levels of power from smart power supply system with energy storage 100. For example, an EV charger 1200 connected to EV 901 with only a little power may receive an increase in power/charge and an EV charger 1200 connected to EV 901 that is almost fully charged may receive a decrease in power/charge. The output power connectors 141, 142, 143, 144, 145 may be of different types (e.g. D/C, A/C) to accommodate different EV chargers or other types of connected loads. The multiple output power connectors 141, 142, 143, 144, 145 can support different types of EV chargers and devices, such as DC EV Chargers, AC EV Chargers, other types of Electric Devices. The system 100 optimizes the power delivered to EV Chargers 1200, and can be connected quickly to EV Chargers 100 for installation and operation. The smart power supply system with energy storage 100 improves the EV charger 1200 by providing faster charging or higher voltage supply than EV charger 1200 alone.

[0088] Accordingly, the smart power supply system with energy storage 100 can provide different EV chargers 1200 with different levels of power, and can adapt to provide different levels of power for different situations. EV Charger 1200 could be 3rd party DC or AC charger, for example. If DC EV Charger 1200 connected, the system 100 has DC power connection 142 to provide the DC power to meet the requirement to operate DC Charger 1200. As long as DC EV Charger 1200 connects to the output connection 142, the EV Charger 1200 can charge the EV in the DC speed. If EV Charger 1200 is an AC EV Charger 1200, the it should be connected to output connection 141 for AC EV Charge Power such as 240V/30A. As long as AC EV Charger 1200 and output connection 141 are connected, then the AC EV Charger can charge the EV in AC mode.

[0089] Fig. 8B illustrates an example smart power supply with energy storage 100 that connects to an EV charger 1200 which is connected to EV 901 to provide fast charging or higher voltage supply through an output charging connector 142 of the main control system board 110. A connected EV charger 1200 may have a connection with high voltage supply from two batteries connected in series via a connection to discharging output power connection 401 of the main control system board 110. This fast charging capability is provided by the smart power supply with energy storage 100 by using the energy stored in its batteries and does not require installing 3-phase AC power connections at the charging location. Installing 3-phase power connections is very costly and not practical or even feasible is some cases. As such, the smart power supply with energy storage 100 which may be fully charged over a long period of time (such as overnight) is then able to provide high voltage DC output connections to EV chargers 1200 to fast charge EVs 901 quickly from the stored energy.

[0090] Fig. 9 shows an example wireless communication board 801. The wireless communication board 801 may wirelessly transmit and receive data. The wireless communication board 801 has a connection to the main control system board 110 for transferring data to and from a server, computer or other network connected device. The smart power supply with energy storage 100 may also transfer data through wired connection 810. The smart power supply with energy storage 100 could be monitored and managed remotely through a live wired or wireless connection. The main control system board 110 is connected to the wireless communication board 801 via connectors 140 and 840. The wireless communication board 801 may transfer some or all activities of the main control system board 110 and some or all activities of the main battery control board 501. The main control system board 110 may send status data about the smart power supply with energy storage 100 to a main server management system that may monitor each component and battery pack status. The main control system board 110 may send diagnostic information about the system and components of the system periodically to the server management system and also send alarms and warning messages if the system has a fault or there is a predicted to occur. Messages may also be sent to select maintenance and operations personnel with actions and recommendations. The main control system board 110 (or main server management system) may send the charging and discharging data to the LCD control board 201 and LCD indicator 200 to display the data for users. For example, the data may include location, capacity of battery packs, remaining charge percentage of battery packs, charging and discharging status, estimated timing data, and so on.

[0091] Fig. 10 illustrates example communications between the main computing server, the system, and other network connected devices. The smart power supply with energy storage 100 is connected to the main computer server 1005. The main computing server 1005 is a data server that may receive data from multiple smart power supplies with energy storage 100. The computer server 1005 may communicate with a plurality of electronic devices to provide data relating to smart power supplies with energy storage 100. For example, the electronic devices may include Tablet PC 1010, Smart Phone 1020, Notebook PC 1030, Computer 1050. The electronic devices may have memory storing instructions and a processor to execute the instructions to provide an interface displaying data relating to smart power supplies with energy storage 100 that is received from the computer server 1005. For example, the electronic devices may have an EV application, which can be referred to as a charger management or operator application, having an interface to indicate status of output power levels and status of discharging of the battery packs. Figure 11 shows an example electronic device 1100. When the system 100 connects to an EV Charger 1200, then the management system can provide an EV Charger management system to exchange data and control commands with the EV charger management application. If a third party EV Charger does not have an internal Management System, then the system’s 100 management system could be used for an EV Charger management system.

The switching matrix 720 is part of the main control system board 110 and main battery control board 501. The example switching matrix 720 shown in Fig. 12 supports four battery packs, two input ports, and two output power connections. The switching matrix 720 may be modified to support any number of battery packs, any number of input ports, and any number of output power connections.

[0093] The switching matrix 720 can be connected between the battery packs 551, 552, 553, 554 and the inputs ports or input connectors 302, 316.

[0094] The switching matrix 720 couples to a current limit 730 component to limit current between the switching matrix 720 and the battery packs 551, 552, 553, 554. The switching matrix 720 has an inter-battery switch bank 721 to selectively connect to any of the battery packs 551 , 552, 553, 554. The switching matrix 720 has a charging switch bank 722 and a discharging switch bank 723 that can individually and selectively connect to the inter-battery switch bank 721. The switching matrix 720 has an input switch bank 725 and an output switch bank 726. The input switch bank 725 can individually and selectively connect to input charging connectors 302, 316. The output switch bank 726 can individually and selectively connect to output power connectors 141, 142.
